OR + FileExist good syntax Topic is solved

[oilali]

Hi, I need quick help.

I'm trying to check two files with "FileExist" function.

Code: Select all

if FileExsist %filename1% OR FileExist %filename2% 
{
do something.
} 
else 
{
do something else.
}

... but I can't use this syntax. (or some similar syntaxes)

What is the right usage of OR statement in AHK in this case? Thank you!

( update: maybe I can't reach my %filename% varible from a previous Label? )

Code: Select all

if FileExist(filename1) OR FileExist(filename2)

;alternatively, and I generally prefer this:
if FileExist(filename1) || FileExist(filename2)

To check your variable do:

Code: Select all

MsgBox, % filename

Ok, But the script is terminated with an error: "The following variable names contains an illegal character"

Previously, I'm working with this variables without any problems...

[jeeswg]

It's related to this:

Code: Select all

q:: ;the two meanings of %var%
b := "c"

a := "b"
MsgBox, %a% ;b (get value of a: b)
a := "\"
MsgBox, %a% ;\ (get value of a: \)

a := "b"
MsgBox, % %a% ;c (get value of a: b, get value of b: c)
a := "\"
MsgBox, % %a% ;(causes error) (get value of a: \, get value of \: ERROR)
return

@oilali: Instead of:
if FileExist(filename1) OR FileExist(filename2)
did you do this?:
if FileExist(%filename1%) OR FileExist(%filename2%)
That would give you that error because as jeeswg pointed out, you wouldn't be passing the contents of the variables named "filename1" and "filename2", you would be trying to pass the contents of variables named, say, "Myfile1.txt" and "Myfile2.txt". Not only are those not your variable names, but they have a character (the ".") that is not valid in a variable name.
